Abstract
Two patients presented to us with very similar clinical and radiological presentation of huge hydatid cysts in the lung and liver. The first patient was an 11-year-old female child and the second one was a 9-year-old male child. The clinical features in both were breathlessness on exertion, pain abdomen, and abdominal distension. Chest Roentgenogram along with computed tomogram of the chest and abdomen revealed presence of thin-walled homogenous large cysts, one in the right lung and two in the liver, in both the cases. Although the liver cysts were of larger size and occupying most of the right lobe of the liver and part of the left lobe, liver function tests were normal. All three cysts were enucleated in the same sitting by a combined thoracic and abdominal approach (thoracotomy followed by laparotomy). After enucleation of the cyst, capitonnage of the cavity in the lung was done and the liver cavities were filled with omentum to prevent collection of fluid and abscess formation. Both patients recovered well, although the second patient required abdominal drain for a long period of 1 month for bile leakage which decreased gradually and eventually stopped.
